BHL is a consortium of natural history and botanical libraries that cooperate to digitize and make accessible the legacy literature of biodiversity held in their collections and to make that literature available for open access and responsible use as a part of a global “biodiversity commons.” BHL also serves as the foundational literature component of the Encyclopedia of Life (EOL).
The Biota of North America Program has produced an online version of its Synthesis of the North American Flora, including local plant distributions, a polyclave or computer key to the families, and a plant image database. The online version allows users to create plant lists of North American Plants, create an online plant set for a location, an online plant list for attribute keying, and research distributions, attributes, and images. The website works best in Mozilla Firefox, is free to use, and contains hundreds of fully populated data fields and millions of vouchered plant references for American counties.
